i am an Indian MB, and I agree with much of what has been posted. I like to think I've treated my nannies well, but though I refer nannies to my Indian mommy groups, I always tell the nanny to be careful - there ARE some mean-spirited bosses out there who want everything but willing to pay nothing. But this isn't race specific - we used to nanny share with an Egyptian girl who grew up here and she was SO mean to our nanny, almost abusive, to the point we actually left the share, but the poor nanny stayed as she needed the job. Point is, you should be careful to get to know future employers - we've always been good our nannies. I am frugal and I usually pay middle of the road rates - but I am always upfront about what I would like to pay and what is expected and if I ask for someone for something more (i.e extra time, extra work) - I pay more for it. But I know Indians who are not that way.
We also have a no-shoe household, more for cleanliness - I work and I just don't have time to keep up with outside dirt in addition to keeping the house clean from the usual inside mess!
